【 摘 要 】

Bufferr solution is one of the abstract chemical concepts so it needs deep study and optimal time to learn it. The purpose of this research is to describe the development of buffer material through flipped classroom learning model. The method used is pre-experiment with one group pretest-posttest design. Research subjects are chemistry education study program students of second semester. The results showed that students are able to respond to the phenomenon and explain the buffering buffer technique based on the working principle; responding to the calculation result of buffer process; and predict the pH of blood in the body based on the effect of activity. This is achieved because students explore the material optimally outside the face-to-face with the help of learning videos, and then discussed in the classroom. Thus the material of the buffer can be studied optimally. The development of buffer materials through the flipped classroom model can contribute to higher order thinking skills.
